a) f(x)= (1,5x2 - 2)2 P[-2|f(-2)]
f ( x ) = ( 1.5 * x^2 - 2 ) ^2
f ´( x ) = 2 * ( 1.5 * x^2 - 2 ) * ( 3 * x )
f ( -2 ) = 16
f ´(-2) = -48
( -2 | 16 )
m Tangente = -48
t ( x ) = m * x + b
Berührpunkt
t ( -2 ) = -48 * -2 + b = 16
b = -80
t ( x ) = -48 * x - 80
Steigung Normale
-1/-48
1/48
1/48 * -2 + b = 16
b = 385/24
n ( x ) = 1/48 * x + 385/24
Alles einmal kontrollieren.
